That's a really serious situation jean, not good for people with ongoing issues.  Is there an ambulance service within reason?  there should be and if the Powers That Be have not allowed for your sort of situation, or things like severe asthma, chest pain and a whole list of other potential killers, then there is something seriously wrong.

On Bruny a medical centre as you have but we also had two ambulances who could be called 24/7.  If the situation was dangerous at night we would transport people down to the ferry terminal where a Police launch would pick them up and transport them to an ambulance in Hobart to go to hospital...

During the day, if it was serious a helicopter was called...

There must be something there for you.  I don't like the idea that you have high blood pressure and you can't get help easily, someone's head would roll if you died due to that system as it is at present, and I would hate it to be you who caused the beheading 😞
